850 W ATX 3.1 power supply

The Super Flower Leadex VII XG delivers 850 W of continuous power and is certified to the Intel ATX 3.1 standard with PCIe 5.1 readiness. It targets builders assembling high-performance desktops that demand stable output during transient load spikes. The full-modular layout uses only ribbon cables for cleaner routing. Buyers who need more than 850 W or require redundant units should look elsewhere.

Full-modular installation with native 12VHPWR

All cables detach from the unit, and the package includes a native 16-pin 12VHPWR cable built from two 8-pin connectors on the PSU side. This avoids the adapter socket that can introduce a weak mechanical joint. The 140 mm fluid-dynamic-bearing fan meets Cybenetics A noise certification. The 150 mm depth fits most mainstream cases, but compact chassis with tighter clearance may not accommodate it.

Efficiency headroom and protection limits

80 PLUS Gold rating guarantees 87 % efficiency at 20 % load, 90 % at 50 % load and 87 % at full load. Cybenetics Platinum adds 89 % to 91 % overall efficiency at 115 V input and 91 % to 93 % at 230 V input. Japanese 105 °C capacitors and a single +12 V rail maintain regulation under heavy draw. Active PFC operates across 90–264 V input. Over-voltage and overload protection shut the unit down before components are damaged.

この商品に関する質問

How do I confirm the unit is running quietly as rated?

The power supply carries a Cybenetics A noise rating, meaning the 140 mm fluid-dynamic-bearing fan stays very quiet under typical loads.

What cables come with the PSU and what must I source separately?

All cables are ribbon-style and fully modular; the box includes a native 12VHPWR cable plus two 8-pin to 16-pin adapters, so no extra GPU cables are needed.

Which efficiency rating should I rely on when choosing this 850 W model?

It holds both 80 PLUS Gold and Cybenetics Platinum certifications — 87 % at 20 % load, 90 % at 50 % load, 87 % at 100 % load per 80 PLUS, and 89–93 % overall per Cybenetics depending on input voltage.
